Abstract

PURPOSE:To contrive the control of a torque value, the antivibration, the save of electric power, the reduction of rotational unevenness, the decrease of a noise and the like by a method wherein the pulse width of driving current pulse is set shorter than a periodical time of an input pulse. CONSTITUTION:An AND gate 5 is provided in each exciting signal line between an excitation mode making-up circuit 2 and a driving circuit 3. The individual AND gate 5 is opening-closing controlled at the same time in common by a pulse width control circuit 6. The exciting signals phi1-phi4 are gated each by a gate pulse GP, so that driving signals phi1-phi4 applied to the driving circuit 3 are turned to signals narrowed in the width by the gate pulse GP, and the supply of the driving current pulse is finished before the following phase advanced pulse reaches or the next drive is carried out. Thereafter, the rotor continues to rotate to some extent due to the inertia and stops of further continues to rotate with the next phase advanced pulse.
